The box at Aylesbury South had (has) 55 levers, 45 of which were comprised of a GWR Double Twist locking frame, but converted to RSCo type direct-tappet locking. The remaining 10 were RSCo / GCR pattern below the floor, with GWR quadrants and levers above. I've got info on opening and closing dates at home, but 1908 and 1992 ring a bell.

Using second-hand frames (in both boxes) is unusual for GC practice and one wonders why frugality was applied here. That frame, incidentally, was of the right pattern to be fitted to the non-operational box illustrated, which is probably just a coincidence but intriguing nevertheless.
Concerning the Met box, I'm not aware that it was officially called Aylesbury East but I will look into this further and also see if I have any dates for that.
Flipper_T_Rox wrote:The theory amongst my colleagues and I is that the fairly unusual ownership situation of Aylesbury Station is probably a factor here. The station was run by not one, but two, Joint Committees - the Met & GC Ry *and* the GW & GC Ry.
With the costs being smeared across all three parent companies, and the resignalling being carried out by, and at the behest of, the Great Central Railway, it is not unreasonable to suppose that one or both of the partners might have insisted on costs being kept to a minimum (my money is on the Met :-)). With the lever frame being easily the single most expensive item in a box, this might offer an explanation for the reuse of the existing frame.
Flipper_T_Rox wrote:A thought now occurs, although one entirely without any evidence. Is it possible that the frame in Aylesbury North box was the similarly reused example from Aylesbury East box ?
Flipper_T_Rox wrote:Confirmation of the name of the Met box can be found in the Board of Trades report into the 1904 crash (link below). Aylesbury East is explicitly mentioned in the description of the site (1st para, page 3), and throughout the evidence given by the various Signalmen involved.

david bigcheeseplant wrote:As for the MSLR box it seems strange to move a signal box just to provide a line side hut, could the whole box been moved and the frame been installed in the north box.
